Windows have changed a lot over the years and their purpose is to protect homes from heat loss. Customer requirements for windows have also changed. When buying windows, they pay more attention to their thermal insulation, durability, safety and appearance. Replacing windows is not only an expense, but also a saving that will be noticed after a long time. Modern windows will last for many years, provided they are installed correctly. The correct window replacement process has several stages.
Before the windows are installed, measurements must be taken. This is an extremely important step because the new windows must fit into the openings. There must be enough space for the window to deform during use. It is also necessary to make space for foam and sealing. If the old windows were installed flush, the new ones should be slightly smaller. The second solution is to enlarge the opening. The window openings must be properly prepared for installation. Loose plaster and mortar must be removed. There must be a layer of foam between the window and the wall to take the pressure off the window. It is extremely important to clean and level the opening thoroughly, and any defects in the wall must be filled with plaster mortar. Polyurethane foam is not the only anchoring element for window frames. Windows should be fixed to the frame with anchors or dowels. The method of fixing the window will be chosen depending on the construction conditions. Many specialists emphasise the importance of dowels, which provide greater stability.
Any gaps between the window frame and the opening are filled with polyurethane foam. The foam insulates the window well and adheres well to most materials. The foam takes approximately 24 hours to harden. Temperatures below 20°C will prolong the curing time and should be taken into account during installation. Expansion tapes are also used when sealing windows. Most window sellers offer to install the windows in addition to purchasing them. The service includes the removal of the old window, the installation of the inner and outer window sills and the processing of the frames. The installation team’s task is to leave the window at least in the same condition as it was before removal. Experienced employees will find the best solutions, which will mean high quality of service.
New windows can be installed at virtually any time. However, the main reason for replacing windows is that they are leaky, which contributes to higher heating bills. Leaky windows can be caused by poor-quality windows or incorrect installation. Windows are also replaced when the frames are damaged, e.g. by fire or attempted burglary. Customers often decide to replace windows for aesthetic reasons. Old windows can significantly reduce the aesthetic value of a house or flat. Sometimes the reason for replacing windows is the desire to buy better quality windows.
